CTS Turbo TT225Q/8L S3 High-Flow Cat

The CTS Turbo high-flow catalytic converter is engineered specifically for the Audi TT 225 Quattro and 8L S3 turbocharged platforms. This direct replacement cat significantly reduces exhaust backpressure compared to the restrictive factory unit, allowing your turbo to spool more efficiently and exhaust gases to evacuate faster. Built with a high-density metallic substrate, it flows substantially better while still providing emissions control. Essential for tuned vehicles where the standard cat becomes a major bottleneck, this component integrates seamlessly into your existing exhaust system without modifications.
